The 3VA51 3P 40A 65KA FTFM Circuit Breaker is a low voltage molded case circuit breaker designed for line protection. It incorporates a thermal-magnetic trip unit, specifically the TM210 model, which provides fixed overload protection at 40A and short-circuit protection at 10 times the rated current.
With a class H breaking capacity, this device is suitable for applications requiring high reliability. It is rated for a maximum voltage of 690V and has a thermal capacity of 65kA at 480V, ensuring robust performance in demanding environments. The dimensions of the unit are 3 inches in width, 5.5 inches in height, and 3.7 inches in depth.
This circuit breaker is designed without lugs and is naval rated for operation at temperatures up to 50°C. It is also compatible with DIN rail mounting, providing flexibility in installation. The absence of integrated earth fault protection and under voltage release allows for simplified configurations in specific applications. The device construction is fixed built-in, suitable for secure installations.
